I apologize if I'm in the wrong forum alltogether, but figured someone might know the answer to this question. Also, I have searched everywhere for the answer, but can't find a fix.
Is this a virus? Or a problem on the server's end? Many sites I visit replace the banner ads (yahoo a lot) with their own (see attached images). In fact, even this site (at the very top) shows me a "electric guitar" link which I'm sure isn't suppose to be there. When you click the "remove this ad" link, you get this url: amp-modeling.info/remove_this_ads.htm
Any help is greatly appreciated. I've ran my virus removers, spy software, etc. without success.
